[pmwiki-users] pagelist.php: Array and string offset access syntax with curly braces is deprecated

[T. Michael Sommers]

I have a brand new installation of pmwiki, from a tarball downloaded a 
few weeks ago.  I am using php 7.4.3 on FreeBSD 11.2-RELEASE-p3.  I get 
warnings saying, "Array and string offset access syntax with curly 
braces is deprecated" for scripts/pagelist.php.

This is a diff that fixes them:
